We’ve got our winners in the “How do I signal a right turn” contest. The question was regarding how to properly and legally signal a right hand turn while riding a bicycle.
In truth, the question was kind of a gimme – there are two correct answers. The first, which most people gave as their answer, is by holding the left arm out, bent at a 90 degree angle pointing up. This is the signal required by the DMV for use in automobiles – which makes sense. This is also what motorcyclists use, so the right hand can remain on the throttle. So yes – right arm at 90 degree angle is correct.
